REVERSE CURRENT RELAY Filed F'env 28, 1954 4 SheetS-Sheec 4 Inventor Iva F, Fed/ 2767 Patented July 21, 1936 UNITED STATES PATENT OFFICE,

This invention appertains to new and useful improvements in electrical relays 01' the current reversing type.

An important object of the present invention is to provide a relay of the type specified which,

because of its simple construction, can be manufactured at low cost.

Another important object of the present invention is to provide a relay which, because of its universal construction, can be employed for use on practically all makes of automobiles.

Other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:--

Figure 1 represents a side elevational view of the relay, with the hood therefor in section.

Figure 2 represents a sectional view taken substantially on line 2--2 oi. Figure1.

Figure 3 represents a vertical sectional view taken substantially on line 3-30! Figure 1.

Figure 4 represents a bottom plan view of the relay structure.

Figure 5 represents a vertical sectional view taken substantially on line 5-5 of Figure 3.

Figure 6 represents a vertical sectional view I taken substantially on line 6-6 of Figure 5.

Figure '7 represents a sectional view taken substantially on line 'l--l of Figure 5.

Figure 8 represents a perspective view of the armature support.

Figure 9 represents a perspective view of the armature.

Figure 10 represents a perspective view of the battery terminal contact mount.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents a base provided with a pair of depending side portions 6--6, in each of which is a pair of openings 1. Extending outwardly from the lower portions of these depending side members 6-6 are the wing members 8, each of which is provided with a slot 9 extending transversely and a slot Hi extending at right angles to the first mentioned slot and opening through one end of the wing, as is clearly shown in Figures 5 and I.

A sheet of insulation i i is placed upon the base 5 and a sheet of insulation i2 against the bottom of the base.

Numeral [3 represents the angular armature mount or support which consists of a base member i4 and an upright I5 at one end thereof, said upright being provided with a slot l6 therein for receiving the depending stop arm H at tion 211; of the pole piece 21.

one end of :the armature plate Hi, this arm being'turned inwardly at its free end to limit the spacing of the contact l9 carried by the armature plate from the contact 20 carried by the battery contact mount 2|. The base ll of the armature mount l3 has a pair of slots 22-43 extending inwardly from the. edge portion thereof for registering with corresponding openings in the base 5, and through these extend connections from the series and shunt coils 24 and 25, respectively. The base I4 is provided with a centrally located opening 26 through which the reduced lower portion 21b of the pole piece 21 extends, the reduced portion extending through a centrally located insulated opening in the base 5. This pole piece 21 supports the core 29 upon which the aforementioned coils are wound. Pole piece 2'! has a shoulder 21a at the juncture of the reduced portion 211) which clamps against the base M of the armature mount about the opening 26 and supports the armature mount in firm rigid relation when the pole piece is as sembled.

The armature plate I8 is formed with a lug 30 and between this and the lug 3! at the top of the upstanding portion l5 of the armature mount is connected a spring 32 which normally tends to support the armature elevated when the coil is not energized.

The battery contact mount 2| is provided with a base portion 33 which is struck to provide depending tongue 34 which extends through openings in the insulation plates 1 l and I2 and also in the base 5 and this tongue is bent laterally at its lower end against the under side of the battery contact terminal 35 in the manner shown in Figure 5, so as to clamp the insulation plates and battery terminal 35 snugly together with the base 5.

I Numeral 36 denotes the generator terminal which is secured to the base by the reduced por- The generator terminal 36 has an insulated opening to receive the reduced portion 21b, and the end of pole piece 2? is flattened. or riveted, as at 21cv against a metal washer 21d, which latter has an insulating Washer between itself and the generator terminal. It will be seen that the pole piece clamps the armsture mount l3 and the generator terminal 36 to the base 5. The generator terminal member 36 is also retained in place by connections from the coils extending downwardly through openings in the base of the armature mount [3 to be soldered or otherwise secured to the terminal 36. Both the terminal 36 and the terminal 36 are provided with binding screws 31. The generator terminal 36 kind battery terminal 35 are flat plates clamped in parallel relation to the base 5.

Numeral 38 represents a hood for disposition over the coils, this hood being provided with a pair of depending side portions a-a having small teats 39 pressed therefrom to project inwardly and due to the slight tensional ability of these portions a-a, these teats will readily snap into the openings l of the portions 6 of the base when the hood is forced downwardly on the base.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, What is claimed new is:-

In relay constructions that eliminates screw connections between the assembled parts thereof comprising a, fiat insulated apertured base formed with depending attaching wings to support the in spaced relation to the object to which the relay is attached, an upstanding pole piece having an intermediate portion extending through an aperture in the base, 2. shunt and series coil carried by the upper portion of the pole piece and above the base, an angular support having one leg apertured and bearing on the base, the other leg of the support being disposed in upright relation with respect to the base, a pair of apertured terminal plates under the base, said pole piece formed with a shoulder merging with a reduced lower end, the latter extending through apertures in the one leg of the support the base and one terminal plate, the lower end 0! the pole piece being flattened against the one terminal plate with the shoulder against the one leg of the support whereby the support and the one terminal plate are clamped to the base, an armature plate rockable on the upright leg of the support in electricel cooperation with the coils and also equipped with a contact, an upstanding mounting disposed on the base and carrying a contact for co-action with the contact on the armature plate, said mounting formed with a portion bearing on the and merging with a tongue extending through the openings in the base and other terpiate, said tongue bent over upon the other terminal plate thereby clamping the mounting and the other terminal plate to the base, and

connected with the upright leg of the support to normally maintain the contacts separated.
